Abstract

Based on characteristics of L-shaped short composite column of concrete-filled square steel tubes(LCSC),research on calculation method and ultimate load-carrying capacity under axial compression for the special-shaped column is done by three methods: superposition theory,finite element analysis and axial compression test.One LCSC specimen is designed and manufactured with depthwidth ratio is 4 for mono column.For the LCSC specimen,ultimate load attained by superposition theory is 3 720 kN;ultimate load is 3 518 kN according to finite elements analysis with shell element,solid element and contact elements;and ultimate load got from axial compression experiment is 3 975 kN.The Results of theoretical calculation,finite elements analysis and axial compression test all show that ultimate loads from three methods accord with each other well.The ultimate load-carrying capacity of LCSC is acquired,and the feasibility of calculation in superposition theory for LCSC is proved.
